Introduction to DATA Step Processing
| Purpose |
The DATA step is one of the basic building blocks of SAS programming. It creates the data sets that are used in a SAS program's analysis and reporting procedures. Understanding the basic structure, functioning, and components of the DATA step is fundamental to learning how to create your own SAS data sets. In this section, you will learn the following:
| Prerequisites |
You should understand the concepts introduced in What Is the SAS System? before continuing.
